Innovations in laser material processing to be presented at SPIE Photonics West

Jenoptik is well positioned for future technology needs with its next generation of F-theta lenses and beam expanders. The products will be presented at the optics and photonics trade fair, stand #1323, from January 31 to February 2, 2017.

13 December 2016

Jenoptik will display its new full quartz crystal lens, the F-theta JENarTM SilverlineTM 170-355-140 (figures represent focal length, wavelength and field size) at SPIE Photonics West 2017. Applications for patent and utility models are pending.

The switch to laser technology is becoming attractive to ever increasing numbers of companies with industrial production processes. Optimized optical parameters and high quality optics in the system employed are essential to ensure the necessary high degree of precision in applications, in the manufacture of printed circuit boards, for example.

The F-theta Silverline lens has a maximum telecentric angle of just 4.9 degrees and a highly homogeneous spot size distribution across the whole of the 100 x 100 mm work area. This large processing area, in combination with the diffraction-limited image quality, allows for increased throughput in comparison with standard lenses available on the market.

Its use with high-powered lasers and ultrashort pulses is also possible, due to the high damage threshold of the lens assured by the quartz material and optimized coating.

Stefan Trippe, Vice President of the Optics business unit at Jenoptik’s Optical Systems division, is convinced of this technological advance: “With our new F-theta, we are providing improved production stability for our customers in current and new fields of deployment. We can ensure the level of precision necessary here by means of the high-quality optics employed, a new patented mounting technology and 100% post-production testing of all lenses. In photonics, there are frequent changes and technological innovations. We adapt our products in such a way that our customers are always in possession of cutting edge and competitive production technology.”

New beam expanders

Jenoptik’s beam expanders have also been redesigned. The first new continuously variable beam expander BEX 1x–4x steadfast similarly meets the changed requirements with regard to precision for laser material processing.

What sets it apart is its innovative mechanical design, ensuring high reproducibility of lens settings as well as the extreme stability of its settings in against shock and vibration. This facilitates simple but safe handling by the user. Diffraction-limited performance across the entire expansion range is standard. This highly robust beam expander achieves a beam stability of less than one milliradian.

In the course of 2017, Jenoptik also intends to launch an additional 1x-8x beam expander in a full quartz version. It will have a large input diameter of at least nine millimeters and is also designed to have a high degree of beam stability.
